Images which show the "Harry Potter" star's head digitally superimposed onto a naked girl's body have reportedly been circulated around the campus of Rhode Island's prestigious Brown University, where she is currently studying for a degree in English Literature.

Watson is said to be seeking out the original fake snap so she can stop it reaching any further, and a representative for the star reveals the actress is growing tired of dealing with so many digitally-doctored pictures.

Watson has faced fake nude snaps several times: in May, her reps demanded the removal of rude photos from the Internet, while a man in Britain was spared jail in August after he created digitally-altered pictures of the actress and posted them on the Web.
